Built from cobalt steel with a bright, uncoated finish, it delivers consistent sizing and smooth surface finish in tough ferrous and non-ferrous materials. The reamer measures 0.3580 inches in diameter (Letter T), carries a 7-inch overall length, and features a straight-cylindrical shank for secure chuck mounting. Six straight flutes cut right-hand with each pass, reducing chatter and improving roundness in through and blind holes. This tool is intended for use by machinists and toolroom professionals in drill press, lathe, or CNC applications requiring tight hole tolerances.\u003c\/p\u003e\n\u003cp\u003eThe HERTEL 72309206 suits production and job-shop environments where Letter T diameter holes must meet close tolerance finishes. It is appropriate for reaming pre-drilled holes in steel, cast iron, aluminum, and similar machinable materials. The 1.75-inch flute length accommodates moderate hole depths typical of fixture plates, bushings, and bearing bores. The straight-cylindrical shank fits standard drill chucks and collet holders commonly found on vertical mills, drill presses, and engine lathes. This reamer is sold and used as a single unit, making it practical for both low-volume repair work and higher-volume production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter T diameter (0.3580 inches) for precise hole sizing in the 0.3500 to 0.3999 inch range\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction provides heat and wear resistance compared to standard high-speed steel\u003c\/li\u003e\n  \u003cli\u003e6 straight flutes, right-hand cut, for consistent chip formation and surface finish\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — ready for use as-received with no coating buildup affecting diameter\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without adapters\u003c\/li\u003e\n  \u003cli\u003e7-inch overall length with 1.75-inch flute length suits moderate-depth reaming operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer for use in drill presses, lathes, and milling machines equipped with standard drill chucks or collet systems accepting a straight-cylindrical shank at the 0.3580 inch diameter class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eChucking reamers are installed by licensed machinists or skilled toolroom technicians. Secure the straight shank firmly in a drill chuck or collet before operation to prevent runout, which directly affects hole diameter and finish quality. Always ream a pre-drilled or bored hole that is undersized by the appropriate stock allowance for the material — do not attempt to remove excessive material in a single reaming pass. Apply cutting fluid appropriate for the workpiece material and ensure the machine is powered down completely before changing or inspecting the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.3580 inches (Letter T)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.3500 to 0.3999 inches (9.00 to 10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72309206\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746451128626,"sku":"72309206","price":86.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acab5d520777aa0c60a932f66ce96a62_5029fde0-c7fc-4e99-9bbd-4b0c30278ca0.jpg?v=1788870379","url":"https:\/\/voomisupply.com\/products\/hertel-72309206-chucking-reamer-letter-t-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
